Hi I'm trying to change access-request: rad_recv: Access-Request packet from host 192.168.3.171 port 39838, id=98, length=142 NAS-Port-Type = Ethernet NAS-Port = 2200961369 Calling-Station-Id = "1:0:24:81:44:41:1f" Called-Station-Id = "dhcp1" User-Name = "00:24:81:44:41:1F" User-Password = "" Agent-Remote-Id = "\000\006\000\025w\262\234\260" Agent-Circuit-Id = "\000\004\000\001\001\013" NAS-Identifier = "MikroTik" NAS-IP-Address = 192.168.3.171 I need to change User-Name similar to this statement: update request { User-Name := %{request:Agent-Remote-Id} } but radiusd prints this: expand: %{User-Name} -> %{request:Agent-Remote-Id} and is searching in sql this string, not correct "\000\006\000\025w\262\234\260" Is there a way to reach this issue in freeradius similar to gnu-radius as shown below? string decode_agent_remote_id() { string agent; string newagent; agent = gsub("%"," ",tohex(%[Agent-Remote-Id])); newagent =field(agent,3)+":"+field(agent,4)+":"+field(agent,5)+":"+field(agent,6)+":"+field(agent,7)+":"+field(agent,8); %[Orig-User-Name] = %[User-Name]; %[User-Name] = newagent+"port:"+field(gsub("%","",tohex(%[Agent-Circuit-Id])),6); return 0; } thanks for advice Libor
